A couple perhaps pedantic points: 1. Some machine models with CPACF have neither processor "books" nor MCMs. The zBC12 and the z114 are examples. 2. Yes, models vary in whether main processor cores have dedicated or shared CPACF elements. The zEC12, for example, has a CPACF element associated with every main core (PU). 3. To my knowledge CPACF is always co-resident on the same microprocessor chip as the PU(s). -------------------------------------------------------------------------------------------------------- Timothy Sipples GMU VCT Architect Executive (Based in Singapore) E-Mail: [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
